Abstract
The present invention provides energy curable compositions that are curable using UV LED radiation. The compositions comprise vinyl methyl oxazolidinone (VMOX), as well as other components generally found in energy curable inks, such as ethylenically unsaturated monomers (in addition to VMOX), acrylated oligomers, and photoinitiators. The compositions are suitable for high speed flexographic or gravure printing.
